While internal parasites are a fact of life in ranching, there are alternative holistic solutions available to assist in their suppression. A high priority should be rotational paddock shift grazing and the encouragement of dung beetle populations. A healthy mixed sward pasture including medicinal forbs is also very important. Access to tannin rich browseable trees such as oak, mesquite, hickory, locust, elm, etc have a strong negative effect on the worms.
Specific plants proven to possess vermicidal/anthelmintic properties are Wormwood (Artemesia), Wormseed or Epazote, Garlic, Senna, Pumpkin seed, Prickly Ash, Monarda, Black Walnut, Tobacco, Neem and Pomegranate root, among others. Incorporating these plants into herbal preparations and/or medicinal grazing cells will go a long way in keeping your animals happy and healthy.
